Is it permissible to rely on a neighbor’s female servant who has no mahram (relative one may not marry)?

The questioner : O Shaykh, there is a large family with a female servant and a male driver, who is the servant’s husband. The servant was forced to travel suddenly due to her mother’s illness. It became difficult for the woman of the house to serve the family members, or it was hard for her to serve them. So the neighbors offered to help by dispensing with one of their own servants. Is it permissible to rely on this new servant, given that she has no mahram and they are in the same city?

The Shaykh : Yes, but the problem is with her people; she has no mahram, and she has no mahram among her group.

The questioner : No, she has no mahram among her people.

The Shaykh : I stop here in this matter.
